About this document
Metal Fissure Defects in Cast Iron by Ranjith Ram is a document available to read on EtoBox.
Fissure defects in castings are narrow, crack-like cavities that often run perpendicular to the casting surface. They have a predominantly dendritic structure inside and are up to 2 cm deep. They form through the precipitation of nitrogen during solidification, which can be intensified by simultaneous precipitation of hydrogen. Castings with thicker walls are more prone to these defects than thinner-walled castings. High nitrogen levels in cast iron from scrap steel feedstock, as well as from nitrogen-conta
